Auto care
Washing your car and
degreasing auto parts at home
can send detergents and other
contaminants through the
storm sewer system. Dumping
automotive fluids into storm
drains has the same result as
dumping the materials directly
into a waterbody.
Pet waste
Pet waste can be
a major source of
bacteria and
excess nutrients
in local waters.
·
When walking
your pet,
remember to pick up the
waste and dispose of it
properly. Flushing pet
waste is the best disposal
method. Leaving pet waste
on the ground increases
public health risks by
allowing harmful bacteria
and nutrients to wash into
the storm drain and
eventually into local
waterbodies.
Septic
systems
Leaking and
poorly
maintained
septic
systems release nutrients and
pathogens (bacteria and
viruses) that can be picked up
by stormwater and discharged
into nearby waterbodies.
Pathogens can cause public
health problems and
environmental concerns.
Lawn care
Excess fertilizers
and pesticides
applied to lawns
and gardens wash
off and pollute
streams. In
addition, yard
clippings and
leaves can wash
into storm drains and contribute
nutrients and organic matter to streams.
Education is essential to changing people's behavior.
Signs and markers near storm drains warn residents
that pollutants entering the drains will be carried
untreated into a local waterbody.
Recycle or properly dispose of household products that
contain chemicals, such as insecticides, pesticides, paint,
solvents, and used motor oil and other auto fluids.
Don’t pour them onto the ground or into storm drains.
·
·
Use a commercial car wash that treats or
recycles its wastewater, or wash your car on
your yard so the water infiltrates into the
ground.
Repair leaks and dispose of used auto fluids
and batteries at designated drop-off or
recycling locations.
·
·
·
·
Don’t overwater your lawn. Consider
using a soaker hose instead of a
sprinkler.
Use pesticides and fertilizers
sparingly. When use is necessary, use
these chemicals in the recommended
amounts. Use organic mulch or safer
pest control methods whenever
possible.
Compost or mulch yard waste. Don’t
leave it in the street or sweep it into
storm drains or streams.
Cover piles of dirt or mulch being
used in landscaping projects.
·
·
Inspect your system every
3 years and pump your
tank as necessary (every 3
to 5 years).
Don't dispose of
household hazardous
waste in sinks or toilets.
Dirt, oil, and debris that collect in
parking lots and paved areas can be
washed into the storm sewer system
and eventually enter local
waterbodies.
·
·
·
Sweep up litter and debris from
sidewalks, driveways and parking lots,
especially around storm drains.
Cover grease storage and dumpsters
and keep them clean to avoid leaks.
Report any chemical spill to the local
hazardous waste cleanup team.
They’ll know the best way to keep
spills from harming the environment.
Erosion controls that aren’t maintained can cause
excessive amounts of sediment and debris to be
carried into the stormwater system. Construction
vehicles can leak fuel, oil, and other harmful fluids
that can be picked up by stormwater and
deposited into local waterbodies.
·
·
·
Divert stormwater away from disturbed or
exposed areas of the construction site.
Install silt fences, vehicle mud removal areas,
vegetative cover, and other sediment and
erosion controls and properly maintain them,
especially after rainstorms.
Prevent soil erosion by minimizing disturbed
areas during construction projects, and seed
and mulch bare areas as soon as possible.
Uncovered fueling stations allow spills to be
washed into storm drains. Cars waiting to be
repaired can leak fuel, oil, and other harmful
fluids that can be picked up by stormwater.
·
·
·
·
Clean up spills immediately and properly
dispose of cleanup materials.
Provide cover over fueling stations and
design or retrofit facilities for spill
containment.
Properly maintain fleet vehicles to prevent
oil, gas, and other discharges from being
washed into local waterbodies.
Install and maintain oil/water separators.
Lack of vegetation on streambanks can lead to erosion. Overgrazed pastures can also
contribute excessive amounts of sediment to local waterbodies. Excess fertilizers and
pesticides can poison aquatic animals and lead to destructive algae blooms. Livestock in
streams can contaminate waterways with bacteria, making them unsafe for human contact.
·
·
·
·
·
Keep livestock away from streambanks and provide
them a water source away from waterbodies.
Store and apply manure away from waterbodies and in
accordance with a nutrient management plan.
Vegetate riparian areas along waterways.
Rotate animal grazing to prevent soil erosion in fields.
Apply fertilizers and pesticides according to label
instructions to save money and minimize pollution.
Permeable Pavement
Rain Barrels
Rain Gardens and
Grassy Swales
Vegetated Filter Strips
—Traditional concrete and
asphalt don’t allow water to soak into the ground.
Instead these surfaces rely on storm drains to
divert unwanted water. Permeable pavement
systems allow rain and snowmelt to soak through,
decreasing stormwater runoff.
—You can
collect rainwater from
rooftops in mosquito-
proof containers. The
water can be used later on
lawn or garden areas.
—Specially
designed areas planted
with native plants can provide natural places for
rainwater to collect
and soak into the
ground. Rain from
rooftop areas or paved
areas can be diverted
into these areas rather
than into storm drains.
—Filter strips are areas of
native grass or plants created along roadways or
streams. They trap the pollutants stormwater
picks up as it flows across driveways and streets.
Residential landscaping
Improperly managed logging operations can result in erosion and
sedimentation.
·
·
·
·
·
Conduct preharvest planning to prevent erosion and lower costs.
Use logging methods and equipment that minimize soil disturbance.
Plan and design skid trails, yard areas, and truck access roads to
minimize stream crossings and avoid disturbing the forest floor.
Construct stream crossings so that they minimize erosion and physical
changes to streams.
Expedite revegetation of cleared areas.
